Title: Improvements in or relating to electrical indicating and/or recording instruments
IPC: G01R1/38
Filed: 1938-10-10
Abstract: 520,138. Potentiometers; compensating instruments for temperature errors. ELECTROFLO METERS CO., Ltd., and COULING, C. W. Oct. 10, 1938, No. 29294. [Class 37] Changes in the dimensions of the chart or scale with variations of humidity are compensated for by means of an hygroscopically sensitive member which varies the angular position of the contact member with respect to the slide wire or resistance carrying member. In the potentiometer shown a pointer or marking device a is displaced across a movable chart b by means of an endless cord d passing round a sheave g which is mechanically connected with a drum e carrying the potentiometer slide wire f. The pivoted normally stationary contact slider h is connected to a member k sensitive to hygroscopic changes so that the contact member is displaced about its pivot when the member k expands or contracts, a restoring spring m being provided. The element k and spring m may be mounted on a bracket to form a complete unit, which may be adjusted in relation to the slide wire to obtain the desired zero position. The chart b is accurately located at the left-hand or zero end by circular perforations, expansion due to humidity changes taking place at the righthand end and being permitted by elongated perforations. The necessary correction therefore varies from zero at the left-hand end to a maximum at the right-hand end. To effect this the slide wire f is helical and the contact member h is pivoted about its'point of contact with the zero end of the slide wire. The following modifications are described in the Provisional Specification. Temperature effects may be similarly compensated for by a thermally sensitive member. The compensating element may displace the slide wire or its drum instead of the contact member. The compensating element may be arranged to displace a pivoted contact member which serves also as a pointer or marker for the chart or is directly connected thereto, the pointer contact member, and compensating element being mounted on a bracket which is displaceable along a slide wire mounted at an angle to the path of movement of the contact assembly. In another modification a travelling contact assembly with a pointer attached thereto is movable along a slide wire which is pivotally mounted so as to be capable of movement controlled by a compensating element, the contact being disposed at a predetermined angle to the slide wire so that variations of the position of the latter relatively to the path of the contact assembly cause the contact to make earlier or later along the length of the slide wire in the direction required.

Filed: 1962-08-02
Abstract: 944,195. Gas turbine plant. A. P. PEDRICK. Aug. 2, 1962, No. 29671/62. Heading F1G. An intermittent combustion type of gas turbine engine comprises a fixed housing O having a number of radial bores in which are disposed plungers F which are urged radially inwardly by means of springs L, the plungers at their radially outer ends being connected to shafts J on which are mounted rollers K, the rollers K engaging the peripheral surfaces of cam plates P and Q. The cam plates are secured to a rotor member R whereby as the rotor and cam plates rotate the plungers are caused to reciprocate in their bores. Air is supplied to the engine by means of a fan A and fuel is injected into the air stream through injectors B, the air/ fuel mixture passing through ducts D in the rotor R and so into the bores in the fixed housing O. The mixture in each bore is compressed as the piston moves radially inwardly, see Fig. 2, and is fired either spontaneously or by a spark ignition device and the combustion gases then discharge through ducts H in the rotor R which is thereby caused to rotate. The gases then discharge on to the blades T and V of a useful power turbine rotor S and finally pass to exhaust. The rotor S drives the fan A and the useful load. The radially inward loading of the plungers F by the springs L may be assisted or replaced by series of circular springs N. The invention is stated to be particularly suitable for use in motor vehicles. Specifications 347,206 and 922,386 are referred to.

Title: Improvements relating to methods of spinning viscose
IPC: D01D1/06
Filed: 1960-08-29
Abstract: <PICT:0909186/IV(a)/1> An apparatus for heating viscose comprises a metal tube immersed in the coagulating bath and constituting the last part of the pipe leading to the spinning nozzle, which tube contains an obstructing body so that the viscose is compelled to flow between the inner surface of the tube and the obstructing body, thus reducing the cross-sectional area of the flowing viscose and increasing its velocity.  As shown, viscose is fed from pump 5 to a metal tube 2 immersed in a coagulating bath 4.  The obstructing body 1, placed near the spinning nozzle 3, may be provided with grooves or spirals as shown, or may be smooth.  The effect of the reduction of cross-sectional area of the viscose and the corresponding increase in viscose velocity is to enhance the heat transfer from the coagulating bath and effect a uniform heating of the viscose by about 10 DEG  to 15 DEG C.  The tube 2 may be made of titanium, tantalum, lead or steel, and the obstructing body 1 may be made of iron or steel.

Title: Improvements in or relating to the treatment of fatty oils
IPC: C01F7/02
Filed: 1947-11-19
Abstract: Objectionable flavours are removed from fatty oils containing vitamin A, its esters, alcohol or any provitamin A, by passing the oil in solution in a non-polar saturated hydrocarbon or mixture of such hydrocarbons through a column of anhydrous activated gamma alumina free from adsorbed water, and then separating the solvent from the resulting bland - tasting oil.  The anhydrous gamma alumina may be obtained by heating a crystalline aluminium tri-hydrate to above 500 DEG  C., the actual temperature and time of heating being insufficient to form the inert a -alumina.  A suitably activated gamma alumina may be found by testing the products obtained at various temperatures above 500 DEG  C. over various periods of heating, by measuring the absorptive capacity of the aluminas for a dye, waxoline blue being exemplified.  The weight of dye in milligrams adsorbed by 1 gram of the alumina may thus be obtained and a preferred product is one having an adsorptive capacity for waxoline blue of between 4.5 and 7.0 mgm. per gram of alumina.  The ratio of the weight of the alumina to the treated oil may be such that the concentration of vitamin in the oil is unchanged by the treatment, a ratio of 3 to 1 being preferred; the ratio may be sufficiently high to give a concentration of the vitamin in the oil, such as a ratio of 10 to 1.  The column of gamma alumina may be revivified by washing with a volatile solvent such as alcohol, followed by heating with hot air, externally applied steam &c. to remove the solvent.  The gamma alumina may be re-activated by heating it to a temperature above 500 DEG  C.  The treated oils specified comprise shark liver oil, dogfish liver oil, whale liver oil, and palm oil containing carotene which is rich in provitamin A.  The non-polar saturated hydrocarbon solvents or mixtures thereof specified comprise petroleum ether, benzene and cyclohexane.
